Hi David,
I don't know what the trick is in thes fast hyb solutions, but if you are
not particularly interested in what the companies' trick is, but just in
trying something with low viscosity and no dextran $ulfate, maybe you would
be interested in an SDS-based hyb solution.
0.25 M sodium phosphate, pH 7.2
1.0 M EDTA pH7.2
7% SDS
1.0 % BSA
I've done hybridizations as short as 6 hrs that work fine (maybe it could
go even shorter, but I have to go home sometime!)
